Micro Jig GRR-Ripper® Basic 3D Push Block System GR-100

Overview

The GRR-Ripper is a precision-guidance 3D Push Block System designed to feed wood on a table saw more safely than you can with your hands alone, and more accurately than with conventional push blocks. The result will be better projects with intact fingers and less waste. With its 3-Directional control, it gives you downward, forward, and lateral pressure on the stock for maximum control and safety.

The GRR-Ripper's patented design eliminates the need for bare-hand feeding, since it essentially acts as a movable blade guard that travels with your hand, rather than being affixed to the back of the table saw, or one that hovers above it. The GRR-Ripper becomes an unyielding barricade between the table saw blade and both of your hands. Maximizing the use of your materials no longer has to compromise your safety. Aside from the safety, you truly get better cuts.

Features:

Results in a perfectly straight cut and safely keeps your hands away from the cutting elements.

I purchased it to use with my other GRR-Ripper to 'leapfrog'. I'm making crown molding and the GRR-Ripper works great on my table saw, especially when making my 45 degree cuts close to my fence. I tried my GRR-Ripper after an episode of kick-back. The Grr-Ripper solved my problem.

BEST ANSWER:The 200 has a Stabilizing Plate that attaches to the Balance Support. It can be used as an additional Fence in some operations. Handy to have it when it is needed. I have Two GR-100's and One GR-200. That way I can have them set up for different functions while doing a project.

BEST ANSWER:The Basic Unit is 7" w X 3 5/8" d X 5" h, and there is an extension piece that adds another 2" to the depth. But that is all neatly packaged. So the final Box may be 8X5X6 minimum. I don't have the packaging anymore so this is a guess. It could be 10 X 6 X 7(8) ??

BEST ANSWER:If you're question is "how narrow", then I would tell you that I've used them to cut strips of 1/32" for edge banding. And as importantly, never felt like I was in any danger of getting my hand into the blade.

I think your asking how thin of a strip you can cut? If so, I think down to a quarter inch just feeding thru a saw. You can set your wood against the fence and adjust each cut as thin as you need. This gripper will make any cut safer and give you a lot of options.

BEST ANSWER:You will need to remove the anti kickback paws and the guard so that the GRR-Ripper can pass over the blade. The rithing knife (splitter) is probably adjustable so that you can lower it to the same height as the blade once you take the paws and guard off. I would suggest you try to adjust the rithing knife so you can continue to use it. It is a safety mechanism that prevents kickback by preventing the board from pinching the blade once it is cut.

The gripper can be and should be used with all safety equipment in place, it is designed to be adjusted so you can pass over the blade if you need to. There are some cuts that you have to remove the safety equipment, but the gripper does not replace safety equipment.

Reviews

I was skeptical at first then read all of the reviews...wow! Flawless design and well built were my first impressions. Then, out to the saw, again, wow! Works flawlessly and allows me to make rips I would not have tried previously, especially on thin stock. Used to get that nervous and apprehensive feeling when ripping thin stuff, and the feeling of "got away with it this time" when I did make the cut...not anymore! Great product, every woodworker should have a pair of these.

I always found ripping thin stock (1/4&quot; - 3/4&quot;) on the table saw a scary activity. Even with featherboards and push sticks, it always felt a little unsafe, or the piece would wander and not end up with a consistent width.The Grr-rippers solve the problem. Period. It's safe, accurate, and you can keep your work piece _tight_ to the fence. It has half a dozen other applications - resawing, flush trimming, jointing etc. as well. Buy two of them, use the hand-over-hand method and you can rip anything like a pro.

I had my reservations about this item, but when I saw Steve Ramsey use it, I knew it had to be decent, so I went for it. I just tried it out today and I must say, I felt very safe on my table saw on relatively small pieces, although it would be wise to have 2 to do the over and under method for longer pieces of wood. It takes seconds to adjust for any type of lumber. Just make sure you have your necessary clearance from the blade versus the grr-ripper. I highly recommend this for any woodworker on almost any type of lumber (I probably would say it won't work on melamine or any type of ultra-smooth surface).

Bought my first one a little more than a year ago. Used it for a very short time, but for no discernible reason, other than maybe not wanting to fuss with setting it up for each cut, went back to my shop-made push stick.Needed to cut some extra narrow pieces of equal thickness, so didn't want to have to move my fence in between cuts. Was about to use my push stick and just let the blade cut into it when I remembered the Gripper. I pulled it out, set it up for the cut and away I went.I did like the added stability and the fact that it helped to keep the material against the fence. I continued to use the Gripper over the next couple months.I became extremely quick at setting it up, now taking a mere few seconds. The stability and control over the material is easily worth those 5 seconds.So now, I have two. I keep them setup as mirror images so that when I need the wider leg against the fence I pick up one, and when I need the narrow leg, I use the other.

Great safety device, easy to build and the DVD aligned with YouTube gives the user several possibilities for its use.

It's plastic but highly durable and even though this is sold in the UK (where I reside), it's better value to buy direct even with the cost of postage even better value when purchased with additional items.

Bought it, had it delivered, assembled it, quickly watched the video, went to the shed and tried it (simulating some previous tricky cuts)....came back inside and immediately ordered a second one.I can see myself ordering more and setting up dedicated combinations.

After a kickback while ripping narrow strips of oak, I ordered the GR-Ripper. It gives me a way of having more control and safety to this task. The instructions that came with the tool are very good. I think I will order the CD for more ideas.

This pusher system works exactly as described. Well designed and constructed. Really a great idea. Wish I would have found this a long time ago - would have avoided a couple bruises on my leg due to kickbacks of very narrow pieces.

Amazing product. Durable and light weight. Rip thin pieces on the tablesaw with confidence. The high clearance and rubberized gripping surface enabled me to make cuts while clearing the blade. This has added a new level of safety to my shop.I also use the product on my router table. I love the level of control the GRR-Ripper offers. Again, this tool has given me more confidence in the workshop and allows me to work safely and efficiently.Not only would I recommend this product to a friend, I am getting a second one to dedicate to the router table.

I have used several push block tools and various safety devices. This is clearly the best. The versatility of the tool adds to its value; the more you use it, the more you realize how to modify it to meet your needs in any specific application. I feel safer using this than ever before. I cannot imagine using my table saw without this tool. I think it is a little pricey, but an essential addition to your workshop &quot;safety kit.&quot;

This is a wonderful product. It is well built and well thought out. I ordered one for work, and after using it, I had to order one for my shopt at home. It only took a few cuts to get used to using it. It gives me great confidence while making those tricky cuts. I also use it a lot on my router table. I highly recommend getting the DVD as well.

Can't imagine someone not giving this a 5* rating. Is the best safety devise you can use. No need for featherboards with this. If you find the legs hard to slide, use a cooking spray or better yet Top Coat.

Simply the best/safest jig i've ever used. Saves my fingers and prevents kickback. I recommend getting two with the DVD and handle bridge accessories. I feel so much safer working on the table saw and router table with grr-ripper. I don't make a cut without it!

Just what I needed! Thank you and my fingers say thank you. Ripping down walnut stock on a table saw to 1/4 inch, with out the fear-factor. Glad I got two grripers like your DVD shows for working longer stock pieces. A great safety tool for all my saws, router, jointer and even the sanding/shaper table. Now my best friend in the shop.

I purchased one years ago at a woodworking show, and have hardly ever used it. 3 days ago I ran the tip of my finger into my table saw blade. I was pushing with my hand, and took my eyes off of the blade for 2 seconds. Mainly just a nick, but it was a wake-up call.I dug my GRR-Ripper out and decided to give it another try. I'll never use my saw again without it. I'm about to purchase a 2nd one, because some improvements have been made over the earlier model that I own.

Thr GRR-Ripper is one of those items that you say, &quot;Why didn't I think of that?&quot; I use mine all the time. Can now make cuts that were impossible without it and so safe. Will be adding the 1/8&quot; attachment and possiblly the &quot;Handle Bridge&quot; It's not like you feel safer, you are safer using the Grr-Ripper!

I have been using the GRR-RIPPER for some time and find this product to be an excellent jig. My last purchase from you is permently set up with 1/8&quot; leg for cutting narrow strips, so now I have 3 units.

I like these even more on my router table than I do on my table saw. I purchased two of these so I could safely rip some longer pieces. Most of the time I've got one set up for the table saw and one for the router table. The price may look steep but once you get them home and see the quality of the design you'll think thy're a bargain. They are remarkably versatile. You do have to adjust these things almost every time you start cutting wood of a differnt size and that burns time. Five stars for quality and safety though! safety is worth the time it takes. I've tossed my push sticks in a junk drawer.

This thing is awesome,cannot give enough praise. Offers safe and precise cuts on every tool imagineable. I got the basic version since i can slowly upgrade as time goes on..... definitely well worth every penny

I purchased the Ripper after looking for a tool to help me with cutting 1/8 inch thick Mesquite strips to inlay in a table top. Simply...It works! It is a safety tool and is engineered to make cuts much easier.

I went into my local Rockler store a few weeks ago with the intent of purchasing the Rockler brand thin rip jig in order to rip thin pieces of wood on my table saw and when I asked the sales associate if they had one in stock, he preceeded to ask me a couple of questions. He then pointed out the Micro JIig GRR-Ripper. He said that is the only tool that he uses in place of his push stick and highly recommended it. So I purchased one and took it home to try it out, watched the DVD and was so impressed that after watching the DVD, hat I went out to the shop to try it out. I can not say enough about how safe and comfortable I feel while using this.I liked it so much that went back to the store and purchased a second one. I purchased the 'GR-200' and the extra plate for the 'GR-100' that originally purchased.All I can say is that if you do not have one, GET ONE. You will not be sorry.
